The improved cut-olf valve which I parts; but when the hose-coupling` becomes have invented ,may have its stationary eletightly screwed up to the valve element the ment secured to this hydrant-nipple in any latter is given the. necessary axial motion, approved way-as, for example, by screwing and such motion is translated into the slida threaded part of the valve into a threaded loo able end wise movement required to open the nipple or by a fused-metal joint. The sta- 5o valve, the whole operation requiring only a tionary part ot the valve is embodied in a few moments time. Furthermore, the valve bearing-ring 12, which is provided with the is packed against leakage in both its open external parallel collars i3 l-fi, adapted to be positioned in the hydrant-nipple so as to occupy a practically flush relation therewith. 'lhis bearing-ring is provided between Said collars with the radial lugs 15, and said ring is adapted to he secured within the nipple 11, so as lo produce an annular space into which fused metal maybe run, so as to form the joint-filling 1o'. This fused metal fills the annular space and encompasses the lugs 15 and the collars 13 1i, whereby the bearing` ring is solidly united to the hydrant against any possibility oi' displacement. This bearing-ring is reduced at its inner extremity, so as to form a narrow annular valve-seat 17 at the inner or rear portion of said ring, said valve-seat lying within the hydrant and adapt` ed for engagement b v the valve-head on elosnre of the latter. The front end ofthe bearing-ring 12 is exposed beyond the hydrantnipple and is likewise reduced, so as to form a narrow annular seat 1S at the front edge of the bearing-ring. Said bearing-ringis formed with a coarse multiple female thread 19,which is formed in the innersurface ofthe ring and is adapted to have its terminals lie at the t'ront and rear ends of said ring, so as to properly engage with a similar male thread on the slidable and revoluble valve element 20. Said valve element is essentially tubular or hollow, and it is provided with the coarse multiple male thread 2l, arranged to have engagement with the female thread 19 of the bearing-ring, whereby the two threads are adapted to coaet to give endwise movement to the valve element when a partial rotation is given thereto. This tubular valve element is provided with an external collar 22 and with a front threaded extremity 23, the latter adapted to receive the metallic threaded hose coupling familiar to those skilled in the art. The collar 22 of the tubular valve element has the studs 24, adapted for engagement by a wrench or other implement in the hands of a fireman, and said collar is provided on its inner face with an annular groove 25, the same receiving a softmetal packing 2U, which occupies such relation to the seat 18 on the stationary bearingring that the parts 1S 26 are adapted to firmly engage when the tubular valve element is moved endwise to its open position, as shown by Fig. 2, whereby leakage of water through the space between the tubular valve element and the bearing-ring is wholly prevented.

The tubular valve element is provided on its inner end with the short legs 27, united by a threaded ring 2S and arranged to form a series of ports 29, through which ports the water is adapted to pass on opening the valve so as to make its exit through the tubular valve element 20. The threaded ring 28 provides for the attachment of the valve-head 30, the latter having an annular llange 3l, which is interiorly threaded in order that the ring 2S maybe screwed thereinto, whereby the val ve-hcad has a slidable connection with the sldable tubular valve element. Said valve-head is formed with an annular groove 32 in the inner edge or face of its annular flange 31, which groove receives a soft-metal packing 33, that lies opposite to and concentric with the valve-seat 17 at the rear ex tremity of the bearing 12, whereby the parts 17 Si) are adapted to have such firm engagement as to produce a watertight joint around the valve-head when the valve is adjusted to its closed position, as represented by Fig. 1.

In the service of the fire hydrant or plug either of the series of cut-olf valves may be opened without disturbing or interrupting the service of any one or more of the valves to which lines of hose are attached. It is only necessary for the fireman to screw the hose-nipple onto the threaded end 23 of the tubular valve element, the latter being at this time in its closed position and exposed to the pressure of the water which is contained in the open fire-hydrant. The pressure of the water on the valve-head and the frictional engagement of the tubular valve with the bearing-ring is sufficient to maintain said tubular valve element in its closed position during-the operation of applying the hose-coupling thereto; but when the hosecoupling is screwed up tight at the completion of the coupling operation the frictional resistance and the pressure of the water on the valve-head is overcome, whereby a partial turn is given to the tubular valve element, and this rotary motion is translated into reciprocating motion by the coacting male and female threads. This endwise movement of the tubnlarvalve element carries the valvehead away from the seat 17 and projects the valve element into the hydrant, so as to expose the ports 29, through which the water is free to pass into and through the tubular element 2O and thence to the hose. The operation of closing the valve is easily and quickly performed, because the partial turn necessary to give the endwise movement to the valve may easily be eiected at the time of unscrewing the hose-coupling or subsequent thereto. In either the closed or open position of the valve the softmetalpackings maintain tight joints, which etectually minimize the leakage of water.

In the embodiment of the invention represented by Fig. 5 the construction of the parts are reversed in some particulars. The stationary bearing-ring 12 is provided with inwardly-extending legs 34, to which is secured the stationary valve-head 35, said legs arranged to form the ports 29. The valve-head is provided within the annular circle of the legs 34 with a soft-metal packing 36, which is secured in a groove formed in the inner face of the valve-head. Instead of forming slots or openings in the tubular element 37 the latter is made in a single continuous tube arranged to fit slidably and removably in the bearing-ring and to present its inner edge in the closed position of said valve element against the packing 36, whereby the solid in- IGC IIO

It is desirable to equip the tire-hydrant with means for admitting air to the interior thereof, wherebythe valves of the hydrant are prevented during cold weather from freezing. I contemplate the equipment of my improved cut-oft valve with an automatic airvent valve; but in this connection it is proper to state that it may be necessary to equip only one of a series ot' cut-od valves provided in a fire-hydrant with such an automatic air-vent. One or more of the air-vent valves may be provided in the cut-off valve; but I have shown only one vent-valve applied in Figs. G 'and 7. A radial hole 89 is provided in the exposed part of the tubular valve element, preferably through the annular collar 22 thereof. Into this hole is screwed a malethreaded bushing 40, the same arranged for its inner and youter portions to have ush relation with the inner surfaces ot the valve elementand with the external face of the colprovided on its inner end with a valve-seat 41. The bushing, fur-Y thermore, is vcounterbored to form the shoulders 42 43, and said bushing receives a tubular valve-stem 44, the latter having the valvehead 45 at its inner end,`said valve-head adapted to ,occupy the seat 4l. Thetubular valve-stein forms an air-admission passage which communicate with the radial ports '46, that are adapted in the open position of the valve to permit the air to flow into the tubular valve element. The valve-stem has a suitable guide-pin 48, that plays in the slot ot the bushing, and on said stemis a stud or pin 47, that constitutes a seat for one end of a coiled spring 49said spring being seatedv against one ot' the shoulders 42 of the bushing. In the normal position of the vent-valve the valve-head is pressed by the spring away from the valve-seat in order to open the airpassage for th'eadmission of air into the interior ofl the cutoff valve, but when said cutoff valve is in serviceY and water is passing through the tubular valve elements 20 or 37 the pressure of the water against the ventvalve head 45 forces the latter to its seat 41, thereby closing the vent-opening.

Changes within the scope ot the appended claims may be made'in the form and proportion ot' some of the parts whiletheir essential features are retained and the spirit of the in.

Vention is embodied. Hence I do not desire to belim-ited to the precise form of all the parts as shown, reserving the rightrto vary therefrom. a

Although Ihave shown and describedthe coarse engaging threadson the bearing-ring The tubular element Y37 has thefcollar.

and the tubular element, I 'donot desire to strictlylimit myself to this construction, because I am aware that these parts maybe united by an ordinary thread-joint.
